A quantitative trait locus for oleic fatty acid content on Sus scrofa chromosome 7

A partial genome scan was conducted, using microsatellite markers, to detect quantitative trait loci (QTL) for ten fatty acid contents of backfat on fifteen chromosomes in a porcine resource population. Two QTLs were discovered on Sus scrofa chromosome, SSC4 and SSC7. A novelty of the QTL for oleic acid was suggested because the QTL was located far from any other QTLs previously mapped for fatness traits.
